Packaging pad structure

ABSTRACT

A packaging pad includes a supporting portion for supporting a piece of goods, and an enclosing portion; the supporting portion includes several different-sized geometric protrusions each having an air room therein; the air rooms don&#39;t communicate with each other; the enclosing portion encloses the supporting portion for enclosing a circumferential side of one end of a piece of goods supported on the supporting portion; the enclosing portion includes several different-sized geometric protrusions each having an air room therein; the air rooms don&#39;t communicate with each other; the protrusions of the enclosing portion are taller than those of the supporting portion; therefore, when a piece of goods is positioned on the supporting portion, one end of the piece of goods and a circumferential side of the end of the piece of goods will be protected from damage in transportation with the protrusions serving as buffers.

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a packaging pad, more particularly one, which consists of several protrusions for touching a bottom and enclosing a lower circumferential side of a piece of goods so as to prevent the piece of goods from getting damaged in transportation.

2. Brief Description of the Prior Art

To prevent goods from getting damage in transportation, packaging pads are positioned over, under and around the goods in packing the goods, which pads will serve as buffers when the goods are shaking in transportation.

Conventional packaging pads are usually made of polylone (expanded polystyrene), and they are shaped to fit a corresponding portion of a piece of goods to be protected.

Such polylone packaging pads are found to have the following disadvantages:

1. A lot of different kinds of packaging pads have to be provided for used on different-shaped goods, and a mold has to be provided for manufacturing each kind of packaging pads of the same shape. Therefore, the manufacturing cost is relatively high.

2. Such polylone packaging pads have a fixed shape and size, and can't be bent therefore they will occupy relatively much space in storage and transportation.

3. Such packaging pads can't be recycled, and are difficult to dispose of because they are made of polylone. Consequently, it might cause harm to the environment to use such packaging pads.

SUMMARY OF THE INVENTION

It is a main object of the invention to provide an improvement on a packaging pad to overcome the above-mentioned problems. The packaging pad of the present invention includes a supporting portion for supporting a piece of goods, and an enclosing portion. The supporting portion consists of several different-sized geometric protrusions each having an air room therein; the air rooms don't communicate with each other. The enclosing portion encloses the supporting portion, and consists of several different-sized geometric protrusions each having an air room therein; the air rooms don't communicate with each other. The protrusions of the enclosing portion are taller than those of the supporting portion. Therefore, when a piece of goods is positioned on the supporting portion, one end of the piece of goods and a circumferential side of the end of the piece of goods will be protected from damage in transportation with the protrusions serving as buffers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1 and 2 show a first preferred embodiment of a packaging pad 1 in the present invention, which is made of a soft plastic material such a PE, and includes a supporting portion 11, and an enclosing portion 12 enclosing the supporting portion 11. When a piece of goods 2 is positioned with a bottom 21 thereof touching the supporting portion 11 of the packaging pad 1, the bottom 21 will be enclosed by the enclosing portion 12 of the packaging pad 1. The packaging pad 1 has a flat bottom so that it will touch an inner bottom side of a packing box 3 closely when positioned in the packing box 3. The packaging pad 1 has several different-sized geometric protrusions 13 on an upper side thereof, which comprise the supporting portion 11, and the enclosing portion 12, and which each have an air room therein; the air rooms of the protrusions 13 don't communicate with each other. The protrusions 13 of the supporting portion 11 have such heights that the top of the supporting portion 11 is rising and falling to fit the bottom 21 of the piece of goods 2. The protrusions 13 of the enclosing portion 12 are taller than those of the supporting portion 11; thus, when the piece of goods 2 is positioned on the supporting portion 11 of the packaging pad 1, the bottom 21 and a circumferential side of a lower end of the piece of goods 2 will be protected from damage in transportation with the protrusions 13 serving as buffers.

Referring to FIG. 3, a second preferred embodiment of a packaging pad 1 includes upper and lower pad members 14 and 15, which are made of a soft plastic material such as PE, and have the same circumferential shape. The upper pad member 14 has an enclosing portion 12, and a middle hollowness 16 enclosed by the enclosing portion 12; thus, when a piece of goods 2 is positioned with a bottom 21 thereof being held in the middle hollowness 16, the enclosing portion 12 of the upper pad member 14 will enclose the bottom 21 of the goods 2. The upper pad member 14 has a flat bottom. The enclosing portion 12 of the upper pad member 14 consists of several different-sized geometric protrusions 13, which each have an air room therein; the air rooms of the protrusions 13 don't communicate with each other. The lower pad member 15 has a flat bottom so that it will touch an inner bottom side of a packing box 3 closely when positioned in the packing box 3. The enclosing portion 12 of the upper pad member 14 is joined to an upper side of the lower pad member 15 at a lower end thereof by means of high frequency wave. Furthermore, the lower pad member 15 has a supporting portion 11 on an upper side, which is inside the middle hollowness 16 of the upper pad member 14, and which consists of several different-sized and different-shaped geometric protrusions 13, which each have an air room therein; the air rooms of the protrusions 13 don't communicate with each other. The protrusions 13 of the supporting portion 11 of the lower pad member 15 are formed with such heights that the upper side of the supporting portion 11 of the lower pad member 15 is rising and falling to fit the bottom 21 of the piece of goods 2. And, the protrusions 13 of the enclosing portion 12 of the upper pad member 14 are taller than those of the supporting portion 11 of the lower pad member 15. Therefore, when the piece of goods 2 is positioned on the supporting portion 11 of the lower pad member 15, the bottom 21 and a circumferential side of a lower end of the piece of goods 2 will be protected from damage in transportation with the protrusions 13 serving as buffers.

Referring to FIGS. 4 and 5, a third preferred embodiment of a packaging pad 1 includes a strip-shaped pad member 17, and a lower pad member 15, both of which are made of a soft plastic material such as PE. The length of the strip-shaped pad member 17 is equal to the length of the circumference of a lower end of a piece of goods 3. The strip-shaped pad member 17 has a flat bottom, and consists of several different-sized geometric protrusions 13, which each have an air room therein; the air rooms of the protrusions 13 don't communicate with each other. The strip-shaped pad member 17 extends along the circumference of the lower pad member 15, and is stuck to an upper side of the lower pad member 15 at a lower end thereof by means of high frequency wave; thus, the strip-shaped pad member 17 becomes an enclosing portion 12, which encloses a holding space 18. Furthermore, the lower pad member 15 has a supporting portion 11 on an upper side thereof, which is inside the holding space 18, and which consists of several different-sized and different-shaped geometric protrusions 13, which each have an air room therein; the air rooms of the protrusions 13 don't communicate with each other. The protrusions 13 of the supporting portion 11 of the lower pad member 15 are formed with such heights that the upper side of the supporting portion 11 of the lower pad member 15 is rising and falling to fit the bottom 21 of the piece of goods 2. Therefore, when the piece of goods 2 is positioned on the supporting portion 11 of the lower pad member 15, the bottom 21 and a circumferential side of a lower end of the piece of goods 2 will be protected from damage in transportation with the protrusions 13 of both the supporting portion 11 and the enclosing portion 12 serving as buffers.

Referring to FIGS. 6 and 7, in packing a piece of goods 2 with a packing box 3, first the piece of goods in positioned upside down, and one such packaging pad 1 is positioned with its supporting portion 11 being over a bottom 21 of the piece of goods 2, and with its enclosing portion 12 enclosing the circumference of the bottom 21. Next, the packing box 3 is positioned around the piece of goods 2, and the packing box 3 with the piece of goods 2 is moved to its upright position, and another such packaging pad 1 is positioned with its supporting portion 11 being over an upper end of the piece of goods 2, and with its enclosing portion 12 enclosing the circumference of the upper end of the piece of goods 2. Finally, the packing box 3 is closed and sealed.
